Permanently damaged joints can now be replaced by Artificial Joints

People may need artificial joints when their natural joints are damaged or worn out due to conditions like arthritis, injury, or degenerative disorders. Artificial joints can help restore mobility, reduce pain, and improve quality of life for individuals experiencing joint problems.
Natural body joints are dynamic structures that are able to repair themselves when damaged, whereas artificial joints are static and do not possess this self-repair ability. Additionally, the materials used in artificial joints may wear out over time due to friction and stress, leading to a shorter lifespan compared to natural joints. Lastly, the body's immune response to artificial materials can sometimes lead to inflammation and other complications that can contribute to the degradation of artificial joints.

To stop their joints aching and to make sure that their cartilage does not wear away.

Titanium and cobalt-chromium alloys are commonly used to make artificial joints for bones due to their biocompatibility, strength, and resistance to corrosion.
Artificial joints, as well as natural joints, basically use the same method as all sorts of machinery does, namely, lubrication.
During sprinting, there is a combination of flexion and extension movements at the joints. The hip joints undergo extension to propel the body forward, while the knee joints experience extension during the push-off phase and flexion during the swing phase. The ankle joints also undergo plantarflexion to push off the ground.
It probably does. The muscles skin and connective tissues will react differently to the extreme heat and may cause arms and legs and other joints to tighten for a few moments. It seems it would be a distressing thing to witness, especially if it is the cremation of a loved one. I doubt that most establishments would allow it.
Yes. Many people have artificial joints, and the Jarvik heart is 'bionic'.
